No optical isolation needed as the ethernet has transformer isolation at both ends, although PoE bypasses this. If you are running pipes around the place, it wouldn't hurt (much) to include a run or two as a backup plan. Even if there is interference from the electric fence, it has a low duty cycle, so the ethernet gear should just retry automatically.<div><br></div><div>Trevor</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Nov 19, 2019 at 6:22 PM Henri Shustak <<a href="mailto:henri.shustak@gmail.com" target="_blank">henri.shustak@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">Hello again,<br>

Also, if you have not started trenching. I have had really good luck with Ubiquity (Chinese) Wi-Fi bridges. They are really quite amazing and at about $250 for a pair including POE injectors it is amazing.<br>
<br>
In the past that kind of out door gear was in the thousands. They also offer longer distance Wi-Fi to ethernet layer 2 bridges.<br>

I was thinking of running optoisolators at either end of copper, however a generous member of this group has offered fibre to the extent that would satisfy this run.
